PACKET-MAKING MACHINE;

To'aZZ whom itmay 6mm.-

Be it known that I, WALTER EVERETT I MoLiNs, a citizen of the United States of America, residing in London, England, have invented certaln newand useful Improvements in Packet-Making Machines, of which the following is a specification.

Hitherto in the making of packets or cartons having one end left open for the introduction of the goods it hasbeen customary Y to employ a blank which has been, prior' to its presentation to the folding or forming mechanism, cut or incised by means of "(1165 or other suitable means so as to form the necessary flaps for closing the open end of the said carton after the contents have been inserted. This method, however, is in practice found to give rise to considerable trouble as the' dies require constant attention in order to keep them in a good condition for cutting. With blanks such as these, moreover, it has been found thatthere is a considerable waste owing to the fact; that a slight displacement ofthe said blank with respect tothe members which are required i. to operate upon it will cause either the malformation of the said carton, or the destruction of the blank,'w hich in either case is wasted. "The present invention has for its object to overcomethe aforesaid disadvantages,and in order that this maybe efi'ected I employ an unincised blank and arrange for the cutting and scoring thereof to take place while upon the former, orplunger,'and at a period its displace1nent.- g

i In order that the invention maybe the better understood drawings are appended in which g Figure 1 is a front elevation of the ma.- chine embodying the present invention. Fig. 2 is a side elevation partly insection of the scoring mechanism. 3 is a sectional plan showing the radially moving cutting blades. Fig. 4c is a detail sectional view on an enlarged scale showing the operation of the scoring devlces. F 1g. '5 shows the class of packet produced by the machine.

Referring to the accompanying drawings in which the invention isillustrated as applied to a machlne having a plunger Wltl'l which cooperate folding means such as that described in myprior'UQ S. application Serial Number 670,137 filed January 9,

This scoring operationiszeifected by means of projections which may"comprise plates 9 :withknifeedges g secured upon each side of the plunger, as shown in Fig. 4, and which plates project slightly beyond the general plane of the surface of thesides of plunger at their "lower edges. j

' Cooperating with the platesor knives just described are hardened plates 9? I disposed as shown in Fig. 4, which plates, project somewhat into the path of the plates 9 so that the edgesflg of the said plates press against platesfgf'and .indent or score}. the i blank atthe base w of the flaps. The plates 9 are secured to the bracketsby screws, as r 1 shown in Fig. 4:, and may have thelr edges slightly rounded, as shown. The upper'ends of plates aresunk flush; with the plunger, butthe recess '9 for theblades isdeeper as shown, the result being. that when pressure; 1'. j

5. In a packet making machine, the combination of a frame, a plunger on which the packets are formed, and a swinging. means operated coincident with the descent of the plunger for folding packet blanks over said plunger, of fixed cutters secured to the said frame, and movable cutters mounted on said swinging folding means to cooperate with the fixed cutters for slitting each blank after being partly folded to form flaps for closing the mouth of the packet.
